Lesson 10
Solving Problems with Trigonometry
Lesson Narrative
In this lesson students apply the concepts of trigonometry to two different situations. In the first, students need to interpret a diagram with limited information to find a way to calculate the dimensions of a polygon. In the second, students are given information about a plane’s flight path, but they need to draw their own diagram as well as grapple with converting units. In each of these situations, students are making sense of problems (MP1) before they are able to use trigonometry to solve the problem.
